Mer-Made level control valves are direct replacements to vacuum DE filter systems.
Mer-Made Float Valves for Surge/Balance Tanks are available in open pipe and in line configurations, with single or dual floats.
Griswold Flow Control Valves provide the required flows to your System automatically - extending filter cycles, and ensuring you are not overwhelming your Filter. We have assemblies for both Filter flow, and Backwash Flow.
Butterfly valves are named for the wing-like action of the flow-controlling disc, which operates at right angles to the flow. The disc has about the same diameter as the connecting pipe, and the flow is straight through, with a low pressure drop. Maintenance is easy due to the small number of moving parts. The butterfly valve can be used either as an on/off or modulating type of valve. These valves may be operated manually, electrically, or pneumatically.
